Introduction: JUST LINE JUST LIGTH #3

The acrylic patterns are illuminated, and two acrylic plates are rotated, giving users a unique experience they never experienced before.

Step 1: Just Line, Just Light #3

The motivation of the work was brought from the artwork. What interesting forms would this work take if it were to be overlapped? And that's what made this work.

Step 2: Project

Our team decided on three types of works and I made the third.

Step 3: Prototype

A number of prototypes have been produced and trial-and-error as to which shapes, colors, and movements can be added to show more interesting shapes, and which structures can be made effectively.

Step 4: Material Body

Adafruit NeoPixel Digital RGB LED Strip 144 LED - 1m 2m * 2

10t 800*800(mm)*2

wood board 700*700 35T*1

Flat belt*2

Flat belt pully*2

Formex*2

Step 5: Material Moving

유성 DC 기어드모터 DH-36 Series (12V) *2

Ultrasonic Distance Sensor - 3V or 5V - HC-SR04 compatible - RCWL-1601*1

L298N Moter drive*1

Arduino Uno*1

Step 6: Material Power&wire

POWER SUPPLY SMPS 50W / DC 12V 4.2A / NES-50-12*2

14awg (3colors) - 10m/each

Step 7: Floor Plan

To design a structure suitable for this work, the drawings are made by cutting wood and ironing the rest of the parts
